These are Uniqlo newborn short-sleeved undershirts and combination undershirts. I bought them in March of this year, washed them, and then gave birth in April, but it quickly became hot, and they only wore them a few times each before they outgrew them. They are white and yellow, so they can be worn by both boys and girls. They are still in good condition, so I hope someone can use them! I will fold them compactly and ship them from home storage, so please forgive any folding wrinkles. Thank you for looking.
